Grinding Mills an overview ScienceDirect Topics
In SAG mill operation, the grinding rate passes through a minimum at a “critical size” (Chapter 5), which represents material too large to be broken by the steel grinding media, but has a low self-breakage rate. If the critical size material, typically 25–50 mm, is accumulated the mill energy efficiency will deteriorate, and the mill feed

Mill (grinding) Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
